DETAILED DESCRIPTION

With reference to FIG. 1, there is illustrated one form of an assembly tool 100. Assembly tool 100 includes a plurality of fitting adapters 101 that are received within a channel 102 of a tool body 103. Tool body 103 is placed within the vice and the jaws as tightened holds the fitting adapters 101 securely. It is understood that the fitting adapters are adapted to hold a fitting during the hose assembly process. With the fitting firmly retained within the fitting adapter 101 and held in the vice the end of the hose is advanced over the end of the fitting. In one form the hose is advanced by a technician manually pushing the hose over the fitting.

With reference to FIGS. 2-10, there is illustrated one form of an assembly tool 200. Assembly tool 200 is operable to engage a fitting 201 with a hose 202. The fitting 201 and hose 202 are coupled with their respective carriers and by the driving of screw 204 through the application of torque to end 203 the hose is pushed over the barbs of the fitting 201. One mechanism contemplated to drive the screw 204 is an impact wrench or a socket wrench. In one alternate form the barbs of the fitting 201 can be driven into the inside of the hose 202. The present application contemplates a retaining end in the tool 200 that includes a plurality of changeable fittings 205 that are configured to hold different sizes and styles of fittings 201. The present application further contemplated the movement of the hose onto the barb by other mechanical means including pneumatic, hydraulic, impact mechanisms in place of the screw 204.

With reference to FIGS. 11-12, there is illustrated one embodiment of the changeable fittings 205 designed to nest with and clamp the fitting 201. A variety of different sizes and configurations are contemplated herein.

With reference to FIGS. 13-15, there is set forth further illustrations of a tool utilizable for coupling a hose with a fitting together.

With reference to FIGS. 16-18, there is illustrated additional material related to a tool for coupling fittings with a hose.

The present application contemplates in one form a tool have the capability to handle a variety of sizes of hoses and fittings. The fittings may be of a variety of configurations and can be straight, angled or of other configurations. A tool may be set up for a fixed mount for a specific configuration of fitting or may be a tool having the ability to utilize a variety of adapters to accommodate many different types and/or sizes of fittings.

While the invention has been described in connection with what is presently considered to be the most practical and preferred embodiment, it is to be understood that the invention is not to be limited to the disclosed embodiment(s), but on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims, which scope is to be accorded the broadest interpretation so as to encompass all such modifications and equivalent structures as permitted under the law.
